You can have kamailio in the front and one pbx per company behind, with possible failover. This presentation from Astricon 2010 talks about how to integrate a proxy with a pbx, in this case Asterisk. http://www.slideshare.net/oej/astricon-2010-scaling-asterisk-installations Might give you good input for further questions :-) Good to hear from you. I just say "IPv6?" :-) /O _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
